Human-Machine-Participation. On the success and shortcomings oft he hearing prosthesis cochlear implant.
No full textHuman - Machine - Participation. On the Success and the Shortcomings of the Hearing Prosthesis Cochlear Implant The recovery of hearing in deafness or profound hearing loss after a cochlear implant is nowadays the rule rather than the exception. However, next to the multiple success with the hearing prosthesis and the associated gain in freedom in professional, social and cultural participation, the person concerned encounter serious challenges. Many of those who have received a hearing prosthesis are burdened by years of strenuous practice in learning to understand with the cochlear implant. Beside this, cochlear users experience after-effects due to the implant surgery such as tinnitus, dizziness or impaired balance. Furthermore, they face a dependence on the few existing medical and technical experts for the care of their hearing prosthesis and a lack of local care concepts for necessary therapeutic support. They also meet various hearing barriers in their everyday life. People at an advanced age currently play a particularly important role due to the high number of fittings. In a reconstructive study, more than 70 people with a cochlear implant were interviewed by means of a guideline interview on their personal experiences with the operating clinics and their newly experienced social, cultural and professional participation in society. The results which were evaluated with the qualitative content analysis showed, on one hand, outstanding improvements in the communicative processes in the users’ direct surroundings. However, on the other hand, the high demands placed on the mastery of technology and a comprehensive personal responsibility in dealing with the hearing comprehension with the prosthesis, which was perceived as disconcerting, led to considerable burdens. This clearly showed the limits of human-machine-interaction
Better safe than sorry? Stated preferences and the precautionary principle for securing drinking water quality in an Italian district
No full textWe apply Contingent Valuation (CV) to investigate individuals’ preferences concerning an alleged contaminant – asbestos contained in fibrolite pipes – which, although not identified so far as a major threat to drinking water, is raising public concern. In the district of Gorizia in Northern Italy, though contrary to the recommendations of experts, mean WTP is high enough to justify an accelerated replacement of pipes as a precautionary measure. However, interviews reveal a strong polarization, and still provide inconclusive recommendations for policy. Our analysis contributes to the debate on the applicability of stated-preference techniques to choices concerning the precautionary principle when highly emotional topics are under discussion
Metabolomics dataset of 44 Propionibacterium freudenreichii for Scoary2
No full text44 yogurts were produced, each by combining a different (sequenced) Propionibacterium freudenreichii strain with the same starter culture (Yoflex® YC-381). The metabolomes of these yogurts were measured using liquid chromatography MS (LC-MS) and gas chromatography MS (GC-MS), the latter measuring the yogurt’s volatile metabolites (volatiles). The aim of this study was to investigate the effect of the pan-genome of the added bacterial strains on the phenotype of the yogurts. We discovered two genes affecting carnitine metabolism.This data was analyzed using Scoary2: https://github.com/MrTomRod/scoary-2/wiki/Output#example-outputFile descriptions:- traits_44_noraw.tsv: corrected and filtered metabolomics data. Includes lc-ms as well as gc-ms volatiles data- traits_info_44_noraw.tsv: metadata about the measured metabolites, e.g. m/z, retention times, descriptions, putative HMDB IDs, etc.- isolate_info_44.tsv: links each sample to its species, in this case, all samples are Propionibacterium freudenreichii.- N0.tsv: a list of Hierarchical Orthogroups (HOGs) that groups orthologous genes together. It was created using OrthoFinder v2.5.4 based on protein FASTA files.- N0_best_names.tsv: maps each HOG to a putative descriptio

Commensurate sliding on a multiple-well substrate potential
No full textIn the context of microscopic solid friction phenomena, we study the underdamped dynamics of a Frenkel-Kontorova (FK) chain subject to an external dc force and a substrate potential defined by the sum of two sinusoidal functions with different periodicities. Particularly, focusing on mutually commensurate choices for the three inherent length scales of the system allows us to consider the formation of commensurate structures during sliding over the multiple-well on-site potential. These structures characterize the dynamical states observed during the chain motion at different strengths of the imposed driving. We comment on the nature of the particle dynamics in the vicinity of the pinning-depinning transition point and investigate the role played by the coverage variable on the depinning mechanism. The dependence of the minimal force required to initiate the chain motion (static friction) on the ratio of the model interaction strengths is analyzed and compared to the well-known case of the Frenkel-Kontorova model
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
